ChIP is a commonly used immunprecipitation technique for mapping the DNA-protein interactions in cells which are crucial for correct gene regulation. In a ChIP assay DNA-protein complexes (Chromatin) are selectively immunoprecipitated using antibodies directed against the protein of interest and the resulting fractions treated to separate the DNA and protein components.

This whitepaper reviews the causes of the three major allergic reactions to single-use glove products in Life Sciences environments, their symptoms, and glove solutions that are available to help prevent adverse reactions.
Based on the membrane foulants, Micro-90®, Micro® A07, or both may be required to clean and return the conditions to their original values. The foulant will help determine which cleaner(s) is needed. If one cleaner is all that is necessary to correct the condition, then that is satisfactory. Sometimes, a pre-soak is useful. In other systems, both an alkaline and acidic cleaner are used for full cleaning. The goal of filter membrane cleaning is to return the flux rate as close to 100% of the original as possible, as well as correct the other pressure and water conditions.
Many different components of a monomer or resin can contribute to the overall monomer functional group properties at a bulk level. Rather than attempting to analyze each component functional group individually, it is easier to approach functional group analysis in polymer manufacturing by evaluating the mixture’s bulk chemical properties.
Polymer production is a multi-step process and each step is an important part of the production procedure. The monitoring of component composition during a process and observation of trends provides guidance as to whether a process is, in fact, under control.
Synthetic polymers offer us an incredible array of properties that can be custom-tailored to applications across a wide range of consumer products. The halogens present in polymers can potentially make their way into the environment as carcinogenic compounds.
NIR spectroscopy is an important tool that can simultaneously optimize process control and product quality, delivering better product to the market at lower cost. Many of these benefits are due to its most popular method of interface – a fiber optic probe placed directly into the reactor system.
Don't get stuck. Get labels that stick and stay legible. Effective labeling can reduce 40 minutes of sample prep to just 5 minutes. That means improved productivity and reduced costs for your lab. Learn more about specimen labeling best practices with Brady's "Error Reduction through Lab Labeling" whitepaper.
Don't get stuck. Label specimens the right way! Brady's "Labeling of Biological Specimens" whitepaper explores the specimen labeling best practices recommended by the National Cancer Institute (NCI). It includes label configurations of four common specimen vessels, preferences for size, readable information and 2D barcodes, and suggested tools for printing, data collection and software.
Fume hoods are one of the most important tools in a research laboratory. The ventilation device ensures the safety of all researchers working in the laboratory by limiting exposure to hazardous or toxic fumes, vapors and dusts. Follow these best practices when it comes to your fume hood budget, facility design and safety requirements to ensure a happy, healthy and productive laboratory environment.
Nitrogen and Phosphorus are the principal elements referred to when discussing nutrient pollution. Current, and past, efforts to control these pollutants have been generally inadequate. Efforts to date have been predominantly “regulation at the pipe” and have not addressed the non-point sources that are the root cause of elevated concentrations of nutrients in ground and surface waters.
Environmental laboratories practice “applied analytical chemistry” by analyzing samples using a list of potential contaminants to determine how much, if any, of the contaminant is present. These contaminants, the methods used to analyze for them, and the maximum amount of contaminant allowed in the sample are defined by regulation.
Commercial environmental laboratories analyze large numbers of samples per day using approved methods, and produce data that need to be technically sound and legally defensible. To remain competitive, commercial laboratories need rugged, automated instruments so they can decrease downtime and increase the number of samples they analyze each day.
In order for corn to become such a major food source across the globe, farmers have relied on improved technology to increase yields year after year. A substantial part of these larger harvests have come from new pesticides that help exterminate weeds and insects that have ruined crops in the past. Here are a few of the most popular and important corn pesticides that farmers and chemists may be interested in.
The demand for cleaner steel grades is driving the need for better understanding and control of non-metallic inclusions in steel. The Aspex SEM-EDS automated inclusion analysis system has been proven as an indispensable modern analytical tool for the measurement of steel cleanliness and the production of higher value-added clean steels.
Automotive manufacturers, and their part suppliers, are increasingly implementing parts cleanliness and contamination control programs that comply with ISO 16232 or VDA 19 standards. These cleanliness standards are typically applied to automotive parts such as transmissions, fuel injectors, power steering pumps, and fluid hoses.
